    actually..hmm I guess you could use AA, nvm but SSS works too

    from that page "SSS Similarity Theorem This theorem states that if the sides of two triangles are in proportion, then the triangles are similar."

    so, it's SSS?

    no jim, all 3 pairs of sides need to form a proportion for SSS to work

    SSS would have been my first choice....but AA works as well (you need to do a bit of work, not much though)

    actually you just need 2 pairs and SSS works

    all 3 pairs of sides need to have same ratio, jim. only 2 side ratios matching wont do for SSS

    hmm this page is odd, they use SSS first, then SAS nvm, i guess it's not accurate go for AA
